CORN HARVESTER AND HUSKER- To @ZL whom, t may concern: A

Be it known that we,THEoDoEE A. OvERBY and JOHN G. OvERBY, citizens ofthe United States, and residents of Mellette, in the county of Spink andState of South Dakota, have invented a new and lm roved Corn Harvesterand Husker, of whic the following is a full, clear, and exact descrition.

This invention relates to cornarvesters, and es ecially to that classwhich are adapted to e advanced in the standing corn and 'implement ofthe class describe which o erate automatically to pull the ears andhusii the same.

The object of the invention is to rovide an ci) which is very simple inconstruction and which isadapted to reach the corn and bring the sameinto the mechanism of the machine without necessitating the exercise of'great care in driving the implement.

Further objects of the invention will appear more fully hereinafter.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

sna ping-chains and the feed-chains. j; eferring more particularl to theparta? and especially to Figs. 1 and 4, the frame '1 of the implement is'of substantially rectangular 5.v jform, as shown, comprising asubstantially'. horizontal forward cross-beam 2 and a 'rearv tail-beam3, the said beams being connectedY by lon itudinals 4. Upon thelongitudinale 4. suita le bearings 5 are attached, in which the axle ofthe implement is rotatably. mounted. Upon this axle wheels 7 and 8A aremounted, the latter of which constitutesl a driving-wheel for the pu oseof transmitting movement to the arts o the implement.

Preferably at tlie left of the implement, as i shown in Fi .A4, at theunder side ofthe frame 1, a tongueeam 9 is attached, and this beamprojects forwardly and inclines somewhat inwardly toward the centralaxis ofthe im lement, as shown. It is preferably secure in this positionby a brace 10, the said brace and the said beam 9 being preferablyattached to the frame at o positesides ofthe drivingwheel 8. At tiieforward extremity of the beam 9 a fork 11 is pivotally mounted at 12,and this fork carries a pilot-wheel 13, which is ada ted to run upon theound and support t e forward portion yof t e frame.

On its outer side to the extremity of the beam 9 there is attached abracket 14, the arm of which is provided With a plurality of lopenings15, which enable the attachment of a shackle 16. To this shackle 16attaches the rear extremity of the tongue or pole 17 of the implement.The aforesaid wheel-fork 1 1. is provided with a bifurcatedforwardly-prof IDO jecting arm 18, to `the forward eXtrem-typt;

this view rep)resents shoes detache f ronithe y 5g which a link 19attaches, the op osite extremity of the said link being attac edpivotally at 20 to the rear extremity of thetongue 17, as indicated.This link is provided with a plurality of openings 21, which correspondwith the openings and may receive a bolt 22, which attaches the link tothe fork 11.

This arrangement for attaching the tongue to the beam 9 affords meansfor adjusting 1o the lateral position of the tongue with respect to theframe, it bei'ng understood that j in order to effect such an adjustmentabolt23,

which attaches the shackle, could be removed, and the shackle could'bemoved and i 5 attached at another of the openings 15.

Likewise the bolt 22 could be removed and the link 19 attached to thefork through another one of the openings 21. The tongue 17 vwouldy be ofany common construction and zo would afford means for attachingdraft-animals, such as horses, for the purpose of advancing theimplement in the field.

Referring now especially to Figs. 1 and 3,

at the forward portion of the frame uprights 25 24, preferably two innumber, are provided,

and these support elevated beams 25 and 26,

which are preferably-disposed askew, as indicated, and transverselyabove the frame.

T hese members 25 and 26 support the rear 3o portion. of asnapping-table 27 As indicated most clearly in Fig. 1, thissnapping-table is.

disposed in an inclined position extending upwardly toward the rear. Theconstruction and arrangement of this snapping-table 3 5 are most clearlyindicated in Fig. 8. It cornprises a pair of oppositely-disposed decksor snapping-boards 28 and 29. These decks are substantially similar inconstruction and placed oppositely, their adjacent edges a short 4odistance apart, as indicated. 4At their u per extremities yokes 30 areprovided, w 'chi are for the purpose of supporting the snapping-table ina manner which will ap ear presently. Upon the up 'er inclined e ges 4,5ofthe members 25 and 26 earings 31 are attached, in which shafts 32 and33 are rotatably mounted, and these shafts project above the beams 25and 26 `and cooperate with them to sup ort the upper extremities of theokes 30, w -ch will hang thereuponfas will e readily understood. Theshafts 32 and 33 are driven continuously when the im lement advances bya mechanism which wi be described more` fully hereinafter, and for rea-6o to above and are connected with the bodies of the shafts throughuniversal connections 32'" and 33h. /Upon the shaft-sections 32a and 33sprocket-wheels 34 are rigidlylmounted, and around these sprocket-wheelssnap-f t5 ping-chains 35 pass. At lthe adjacentlower clearly in Fig. 8,these brackets are preferably corners of the decks 28 and 29 smaller srocket-wheels 36 are provided, to which t e lower Iportions of thechains pass, as indicated. Other sprocket-wheels or tighteners 37 areadjustably mounted in slots 38, and these engage the chains in suchmanner as to enable the tightness of the same to be adjusted, as will bereadily understood.` Along the outer edges of the decks 28 and 29.guide-strips 39 are attached longitudinally, between Which ythe chainpasses in its down.- ward course.l The upper courses a of the chainspass between guide-strips 40 and 41, the latter of which strips at theiru )per extremities are bent around the perip Aeries of 8o thesprocket-wheels 34, attaching to the outer edges ofthe decks, asindicated. From this arrangement the guide-strips 41 constitute guardsfor the sprocket-wheels. At their upper extremities the guide-strips 4085 Vturn inwardly toward the decks and attach rigidly thereto, as shown.The Taforesaid sprocket-wheels 36 are rotatably mounted on studs 42,which project .outwardly from guard-plates 43, said guard-plates resting9o oosely upon the upper surface of the dqks 28 and 29, near the lowerextremities therepf, and at their inner edges. These guardlates 43 arepreferably substantially circu ar in form, as indicated, and providedonv their outer edges with flanges 44, which Vconstitute guards forthejsprocket-wheels. Near their upper edgesthese guard-plates aresuspende freely upon links 45, which are hun pivotally at 46 uponth'eupper faces of the ecks. Both these guardsplates 43 are freely hungupon the links 45, and theyare normally constrained toward each other bymeans of s rings 47, the said springs being attached to slide-bars 48,the same being guided transversely of the decks by means of cleats 49,attached to the faces .of the'decks, as shown The lower extremities ofthe aforesaid guidestrips 41 attach at the eripheries of theguard-plates 43 and constltute substantially tangentiall continuationsvof theaforesaid flanges 44. The aforesaid guide-strips 40 attach to theplates also, as shown, and with this arrangement the space between theguide-stri s constitutes substantially guideways for t e up er runs 35aof the snappingchains. In or er to secure the guide-stri is 40 and 41.throughout their length', light brackets 50 are provided, which attachat the adjacent edges of the decks 28 and'29 and project into the spacetherebetween. The projecting portions of these brackets are formed withupwardly-disposed forks 51, which attach to the guide-stri s rigidly inany 'suitable manner. As in icated most roo IOS

disposed in an alternating or staggered .relation, so that the bracketsattached to one of Il l essere may be resiliently attached to the decks.

With this arrangement the bodies of the brackets constitute slidesguided under v cleats 52, each of said brackets having anupwardly-turned tail53, through which an eyebolt d passes, the saideyebolt serving to attach a spring 5.5, which is connected to the decknear the inner edge thereof and operare -very c early illustrated inFig. 1.

ates to return the guide-strips to their normal positon if, they areforced inwardly.

In Fig. 10 is illustrated one of the links of the snappingJchains. Thebodies 56 of all these links are of substantially the same form at oneside and hooks 58 at the opposite side, so that the links may beassembled into a complete chain. The links are preferably all formed attheir upper portion into integral fiat plates 59, and at the rear edgeof each plate 59 a liange 60 is provided, which projects upwardly andsubstantially at right angles to the plane of the plate. These flanvesand their relation to the chain At suitable intervals the iianges areformed of enlarged or extended form, like the flange 61. (Shown in Fig.10.) The purpose of these special links with these extended flanges'willpresenting wrists, 57

` shown.

Arrangement is made for adjusting the distance between the adjacentedges of the decks 28 and 29. To this end beneath the snapping-table atruss 62 is provided, the same consisting of arms'63, attaching,respectively, to the under faeesof the decks, and these arms are heldapart by a strut 64, The strut 64de preferably given a Vshort taper orpoint 65 at its extremities, and these points are received incorresponding recesses formed in the adjacent faces of the arms 63. Onopposite sides of the strut 64 tie-bolts 66 are provided, which connectthe' arms 63 and enable the distance between the decks to lbe adjustedby means of nuts 67, carried by the bolts. ln this connection it shouldbe und erstood that if one bolt should be tightened and the oppositebolt loosened the arms 63 would be adjusted upon the points 65 asfulcrums.

The arms 63 are connected by braces 27b with the rear side of thedecks-28 and 29, as

At the lower portion of the snapping-table a pair of braces 68 and 69are provided, the same being attached, by-means of expanded feet 70, tothe rear side of the snap- These braces are most clearly shown in Figs.1 and 4. They are connected with the decks 28 and 29 by braces 27l andextend rearwardly,as shown. AA brace 68.

passes an eyebolt 72, and its extremity is oH- set laterally and mountedupon an adjustingscrew 73, as indicated most clearly in Fig. a, Byreason of this adjustment the position of the snapping-table may bealtered with res ect to the central line of the implement.`

or a purpose which will appear more fully l hereinafter near theirforward portions the braces 68 and 69 are offset outwardly, as at 74, soas to inclcse a rudimentary opening 75, Referring now to Figs. l and 8,to the forward lower edges of the decks 28 and 29 oppositcly-disposedshoes 76 are attached, preferably by means of hinges 77. These s oes arepreferably of substantially the form shown, having bodies disposedsubstantially in the same direction as the decks 28 and 29 and divergin`noses 78, said noses being referably rounded, as indicated. These s oesnormally occupy substantially a horizontal position and are secured bymeans of diagonal braces 7 9, which braces' are attached to the uppersides of the decks by means of suitable bolts located at 80. In order toenable the position ofthe shoes to be adjusted within certain limits,the upper extremities of the dia onal braces 79 are preferably formedwit slots 81, which receive the bolts at S0, as will be readilyunderstood.' Upon the upper side of the shoes 76 feed-chains 82 are 95provided, which operate to advance the stalks of corn into the spacebetween the shoes and toward the space between the decks. ln thisconneetionit should be observed that the said shoes are disposed apartroo so that the adjacent edges of their bodies arev substantially inalinement with the inner edges of the decks. To the upper sides of thebodies of the shoes 76 inclined plates 83 are attached, which areelevated toward the rear, and to the upper faces of these platesbrackets 84 are attached, the said brackets being offset upwardly andcarryin rotatably sprocket-wheels 85. These sproc et-wheels are drivencontinuously by universal connecr 1o tions 86, which lead from theaforesaid sprocket-wheels. This universal connection is 'of any commonconstruction, such as that indicated in Fig. i2. The inner courses 87 ofthe chains 82 of course move upwardly, 1 15 and the chains are providedwith outwardlyprojectin dogs S8, which preferably curve rearward y, asshown. These dogs are disposed upon the chain so that they advancesubstantially opposite to each other and 12o when the chains are inmotion operate of course to feed the stalks rearwardly in the directionof the snapping-table. In order to revent any possibility of the stalksof corn eing carried around the sprocket-wheels 85 12 5 with the chains,oruard-springsSQ are provided, which attac 1 to the inner edges oftheshoes, as indicated, and the bodies of these springs are preferablycurved inwardly, cor!- verging, as shown, so as to present a narrow 13oopening through which the stalks must pass to go into the space betweenthe decks. AThe inner courses 87 of the chains are guided by means ofsprocket-wheels 90 91, so that the dogs 88 may pass around the inneredges of the shoes, as shown, projecting beyond the same, so as tofacilitate the feeding movement. At the inner edges of the shoesguard-strips 9.2 are provided which assist, in guiding the chains."While the lower portions of the courses S7 of the chains are disposedsubstantially horizontally, lying -upon the upper faces of the slices,the rear ortions beyond the sprocket-wheels 90 ine inc upwardly, so asto pass over the sprocketwheels 85, which are slightly elevated, asindlcated.

From the construction described above itV should be evident that as theimplement is advanced in the standing corn the stalks of corn may passinto the converging'space betweenythe noses 78, whereupon he continthespace between the inner edgesof the snapping-chains i235 is too small toallow the ears to pass The detached ears are then caught by the wings oranges 61 aforesaid and `advanced/upwardly toward the husking mechanism,which will be presently de scribed. f

The manner of mounting the snapping-tw ble by hangin the same upon theyokes'O in the manner fuly described. above very materially facilitatesthe entrance of the stalks into .the space between the decks. In thisconnection it should be understood that when the'stalk strikes vupon theinclined inner edge of either of the noses 78 itis not necessarythatt-he stalk should be bent from its" course when the direction of.the imple ment changes in order to effect its passage into the spacebetween the decks. This follows because the snapping-table moves freelyeither to the ri ht or to the left upon the yokes 30. In t is way thesnapping-table adjusts itselfl automatically, as it were, to theposition of the stalk. This arrangement for mountin' the snapping-tableis considered highly a vantageous,'as it obviates any necessity forcarefully driving the implement and enables the machine to adapt itselfreadil to the cornstalks which are not in true a inement with the row inwhich they stand or which ma have had their bodies forced toA one sidebyt e wind.

The husking mechanism will now be described. This mechanism comprises apair of oppositely-disposed cylinders or rolls 93.

('iiilustrate'd most cleariy in Figs. 1, 3, and 5.) Theyare disposed inthe same general direcesas-ic' in alinement with the center of the spacebe-4 tween the decks 28 and 29. The forward and upper extremitiesv ofthese rolls are formed into-tapered snouts 94, which are rotatablymounted upon gudgeons carried in brackets 96, the said bracketsbeingattached, respectively, to the aforesaid beams 25 and 26. The roll93, which is'located to the right of the implementl as viewed in Fig.3,'constitutes 'the main husking-roller. Its shaft 97 is rotatablymounted in a bearing 98, which bearing is rigidly secured to the upperface of a transverselydisposed husking-.beam 99, which beamis supportedupon theframe of the implement in any suitable manner. Near-their lowerextremities the husking-rolls 93 .are provided with gearwheels, 101,which mesh together in'order that the rotation of the main husking-roll93. will be imparted to the roll 93h. vThe gearwheel 101 meshes on itsouter side with a ear-wheel 102, which latter is carriedrigidly y thelower portion of the, aforesaid sectional shaft By reason of thisarrangement the rotary movement of the huskingroll 93 is imparted'to thesnapping-chain, which is ,carriedupon the deck-29. A similar gear-wheel1Q3 is provided, which is attached to the sectional shaft 32, and -thisgear-wheel meshes with thegear-wheel 100,

so that the snapping-chain carried u on the deck 28 is continuouslydriven with t le rolls.' The lower extremity of the shaft 33'is rota'-tably mounted in a suitable bearing 104,l

which, like the bearing 98,is rigidly attached to the husking-beam 99.-The trunnions of the husking-rcll and of the shaft 32 are mounted inbearings 105, which are formed.

upon a floating bracket 106, the said bracket@ being mounted' so as ltemove freely upon pivoted links 107, the lower extremities f whieh` linksare freely attached to the face of the hiisking-beam 99.' A spring 108,which is attached to the bracket 106, has its oppooperates normally tomaintain the roll 93b against the roll 93%.

The tace of the roll 93a is I2()v For this purpose the.

site end connected with the beam 99, and i ...I-nvidd with aplurality oflongitudinall '-jfgisposed ribs 11'1, which ribs are preferab ythreeginbnuinber and disposed at equal dis'- t'aces apart, asindicated.. At or nearits ex- ;A temitiesannular shoulders or rings 112are v,forrr'ieh 'the outer faces of whichroll upon thefopposingvface ofthe roll 93h. From this arra ement there normally exists a space.between the faces of the rolls, and through 1o thisspace atregulagintervals the ribs 111 pass. vAdjacent to one of the ribs 111 a.stripper 113 is attached., and this strip er consists kot an elongatedfiat bar, at the orward edge of which u wardly-inclined teeth v 11,4fareprovided.;T 's stripper 113 is attaehed justin advance of `one oftheribs 111 'andro crates to yrernovethe husk of an ear lying'in the sv acebetween the rollsrf. Strippersjll, similar tothe stripper 113aforeoaf'said', 'are attached to the face of the roll 93h,

these are disposed in such position that [as thefroll's rotate they passthe point of conta'ctjbetween the rolls'at oints intermediate.

' 'bfejtween the ribs 111. rom this arrangeasfrhcntas the rolls rotatethe intermediate or v'depressed faces 116 voi' the roll 93'l comesuccessivel into the lpathsof the strippers 115,

carriedy the rol 93;y The relatlon of the -`"1"ollsintlis res ect ismaintained, of course,

'goiby reason oftiie fact that the gear-wheels :10Q-101, which theycarry, areof equal diameten I ,l

ard-boards 117 are'provided, located, re-

'1". spectively, at each` side of the rolls with their .flower-edgesadjacent to the faces of the rolls,

as indicated.' lIt should' be understood that :the rolls rotate towardeach othergabove in such a manner as to passthe husks downiwwt'rardly.between them. l

- In orderto dispose of the ieces of husk which tend to accumulate in te s ace above the rolls, avhusk-feed 118 is provided. This husk-feedlismost clearly illustrated in Figs.

a 5 1 and 2 l and its construction comprises a body or board 119, placedin an inclined position above` the lower or rear ortions of thehusking-rolls' and it is dispose in a substant'iallv vertical plane. Atits lower extremity 5o the od or board 119 is provided with opositely-dlsposed forked brackets 120, the orks of 'which are supportedupon a' transverse shaft 121, as indicated most clearly in Fig. 2.

' This'shaft 121 is mounted upon a rudimen- 1 5 5 tary Z-bar 122, thebody of which attachesto the upper lr'ace of oneof the inclinedguardvboards'1'17, and to the arms of this Z-bar brackets 123 'areattached, the same being provided with bearings for the shaft, as illus-6 o trated.

l 'Toi-the shaft '121 a sprocket-wheel 124 is ed', which sprocket-wheelaffords means the shaft continuously as the im- `plein l-advances. Thismanner of l Vbe described more Afully hereinafter. `To

board,- as indicated. Preferably sprocket-wheels 125 and 126 asprocket-chain As indicated most clearly in Fig. 5, inclined advance thehusks wlth which they come in lrolls, from whic portion thereof whilethe ears of corn gravi- .one extremity `of the shaft 121 a second` isprocket-wheel 125 is attached, and 'this sprocket-wheel is insubstantial alinement with the body-board 119 and is disposed inalinement with a corresponding sprocket- 7o wheel 126, which lattersprocket-wheel is located at the upper-extremity of the lbodyarran ementshould be made for adjusting the istanc`e between these sprocket-wheels.To 7 5,v this end the sprocket-wheel 126 is preferably :mounted upon abracket 127, having a slot 128, by means of which ad`usting-bolts 129attach the bracket to the ody. y 0ver the 8o 130 passes. When themachine is advancing, the lower course 131 of this chain is movedupwardl so as to oplpose the natural gravitation of t e ears and usksvtoward the 4. ower portion of the husking-rolls. To the 85 chain 130 aplurality of outwardly-projectin horns 132 are attached, and the bodies0% these horns reerably curve rearwardly with respect to t e directionof advance of the chain, so that the -tips of the horns, which aresubstantially strai ht, dispose themselves substantially paral el withthe axes of the husking-rolls asI they advance with the lower course 131of the chain. The extremities of most of these horns are preferabl plainand 49 5 sim ly pointed,but certain 'of the orns, Arefera ly every thirdhorn, is provided wit an outwardly-turned tip forming a serrated hook133. This husk-feed is for the u ose of initiating the separation of thehusis om the ears and from the shelled ain which passes through-thehuskin -rol s. In'this connection it should be un erstood that as thehorns 132 move upwardly they operate to cont'act rin an upward directionalong the arrangement there is a tendency for the rincipal portion' ofthe husk to pass througlh the rolls near the upper I I O' tate toward'the lower extremity -thereof and are dischar ed and disposed ofin a maniner which will e described more ly hereinater.

In order to stir the ears of corn asy the lie upon the rolls at suitableintervals, the c vain '130 is provided with stirrersor stems 134,

which pro'ect downwardly at the lower course of t e chain and disturbthe ears as t the stems pass upwardly. At the lower ex- :zo tremity ofthe husk-feed a shield is rovided, which shield consists of a bent p atewhich conforms substantially to the outline of the'path ofthe points ofthe horns 132, o i erating as a guard for them as will be readily 1 z 5l understood.

"Arrangement is' made for adjusting the ,head of the husk-feed in itsrelation to the rolls 93. AFor this purpose the, body-board 1 19 ismounted upon inwardly-bent stand- 13o roo l Below the husking-rolls aseparator 1.38 is provided, and this consists of a body, prefer-- ablyconstructed of wood, having a rearwardly-inclining bottom 139 and sidesor side boards 140, which are disposed substantially vertically, asshown. Between the sides 1:40 a pair of sprocket-rollers 141 and 142 arerotatably mounted, the same being respectively located at oppositeextremities of the separator. The roller 142 is carried upon brackets143, which have slotsv 144, through which bolts pass, as willbe readilyunderstood, for the purpose of enabling the position of this roller tobe adjusted. Over the rollers 141 142 a conveyer-belt 145 passes, andthis belt comprises oppositely-disposed sprocket-chains connected bytransverse slats 146, the said slats being disposed ap`art, so as topresent spaces through'which the shelledl grain may pass. At suitableinter- `vals the slats are provided' with upwardlyprojecting pins 147,which pins operate to advance the husks toward the upper'or forwardportion oi the separator. In this connection it should be' understoodthat the upper course of the conveyer-belt 145 moves forwardly and inthe direction in which the implement advances, it being also understoodthat the conveyor-belt is continuously driven while the implement moves.The mechanism for driving this belt will be described more fullyhereinafter.

The lower edge of the separator-bottom 139 is disposed just above areceiver 14S, into which the shelled grain is ejected from the separatorby the pins 147. At this edge a guard 14E) is provided, which is ofcurved form, as shown in Fig. 2, and comprises a plurality ofupwardly-disposed curved blades presenting openings 150 therebetween.This guard is for the purpose of preventing small pieces of husk frompassing into the receiver, should any such pieces find their way to thispoint of the separator. The pins 147 are disposed upon the slats 146 insuch arrangement that'the pins pass into the aforesaidl spaces 150, andin this manner theyV operate to clear the guard of any pieces of huskthat may tend to adhere thereto andclog the s311116.

The body of the separator is located in a suitable position beneath therolls 93, so that all grain and husks that pass between the rolls willfall upon the upper course of the oonveyer-belt. The shelled grain willof course 'find its way through the spaces between the slats andeventually fall upon the inclined bottom 139. The husks, however, pr theprincipal portion thereoiI will be advanced upwardly and ejected at theupper portion of the separator, passing between the arms 63 aforesaidand through the rudimentary opening 75, formed between the braces 68 and69. The adjustment of the roller 142 evidently enables the tension ofthe conveyer-belt to be readily adjusted. y

Though the conveyer-belt operates to eject the principal portion of thehusks at its upper extremity, some pieces of husk find their way throughthe same and are carried rearwardly uponthe lower course of theoonveyer-belt.

- Arrangement is made for ej ecting such pieces o f husk near the rearportion of the separator. To this end there is provided an ejector 151,the construction of which is most clearly shown in Figs. 5 and 6. Itconsists of a plate of substantially rectangular form, the rear portionof which is formed into a sleeve 152,

vsurrounding the axle 153 of the sprocketwheel 141. At its forward edgethis plate is supported upon a transverse bolt 154, and at one edge itis formedwith a projectingwing 155, which wing is composed of aplurality of prongs or tines 156, the axes whereof-are disposedlaterally with respect to the direction in which the conveyer-beltadvances. This ejector operates as a guard to prevent small pieces ofhusk from wrapping around the axle 153 and also`operates to eject thehusk as the same advances upon the plate. To this end an opening 157 isprovided through the adj acent side and through which the pieces of huskmay ind exit. The tines 156 operate. advantageously to support the husk,while they allow the grain to fall between them if" there should be anywith thehusk, the-said grain then passing to the inclined bottom 139.

The receiver 148 constitutes an inlet to an elevator 158, within thebody of which a chain or belt conveyer 159 operates continuously, thesame being driven from a shaft- 160 and running over the sprocket-wheels161 and 162. To the chain 159 a plurality of wings 163 are attached, andthese wings at suitable intervals are replaced'by cups 164. The wingswill operate to elevate the ears of corn which drop into the receiver,and the cups 164 pick up the shelled grain which accumulates atthebottom of the elevator,

IOS

raising the same, as will be readily understood. At the upper extremityof the elevator a substantially vertical board 1.65 is provided, whichconstitutes a guide'for deleoting the shelled grain vertically downwardintoa wagon, which would be driven at the side of the implement.v

Arrangement is made for tightening the chain 159. To this end the uppersprocketwheel 162 is mounted upon a shaft 166, carried in a slot 167,said shaft being rotatably mounted in a bracket 16S. `his bracket has alongitudinally-disposed slot 169, through which it is attached to thebody oi', the clevat'or by suitabie bolts, and the bracket is mostclearly in Figs. 1 and 2.

esame adjustable longitudinally by meansl of anad` justing-screw 17 0.

The arrangement for driving the moving by a spring 175, as shown in Fig.3, but.

Awhich may be opened at will through the medium of a bell-crank lever176, which attaches to a controllingdever 177 by means ofv a link 178.The said lever 177 is refera'bly mounted forwardly upon the mem. er 25and should be located in a convenient position with respect to the seat179, upon which the driver sits. An auxiliary chain 180 is driven froman intermediate point, as at the sprocket-wheel 186, upon the auxiliaryshaft 172. As indicated most clearly in Fig. 7, this chain passes overan .elevated guide s rocket-wheel 181, from which wheel the c ain passesdownwardly and over the aforesaid sprocket-wheel 124, which wasdescribed in connection with the husk-feeder. This guide sprocket wheel181 is preferably mounted upon a pivoted arrn182, which is held firmlyin position by an adjustable diagonal' brace 183, the said arm and saidbrace being attached to the adjacent guardboard 117. Continuingdownwardly below the sprocket-wheel 124 the chain passes over asprocket-wheel 184, which is carried rigidly by the axle of thesprocket-roller 141. Below this ioint the auxiliary chain 180 passes toa gui e sprocket-wheel 185, returning to the auxiliary axle, where itasses over a sprocket-wheel 186, lcarried y the same. Through the mediumof bevel-gears 187 and the sprocket-wheel 185, which are rigid on astub-shaft 18531, the axle'is driven, and this actuates theelevator-chain 159, as shown The aforesaid shaft 97 of the mainhusking-roll 93EL extends below its bearin 188, as indicated in Fig. 3,-and carries rigi ly a bevel gear-wheel 189, which is driven from nsecond bevel gearwheel 190, the latter of which is rigidl mounted uponthe aforesaid auxiliary sha t In order to enable thehusking-rolls to beturned by hand whenthe clutch 174 is disconnected, said shaft 97 isprovided with a suitable hand\vheel 191.

In orderto prevent ears ofvcorn from being caught between gears 100 and101,'we provide a Y-sha ed guard 100, which is attached to thehuskingybeam 99 and the same having branches 100, which lie over thefaces of 'the gears, as will be readily under# stood. f v

' Arrangement is provided for raising and any lowering the frame at itsforward portion, so as to adjustment. For this urpose a handever 192 isprovided,`as indicated in Fig. .1, the same being pivoted to the forwardportion .of the frame 'at 193. bell-crank lever, the short arm whereofattaches to a link 194, which link isl pivctally securedlte a mounting195, rigidly carried by theV tonguebeam 9. In connection with thehand-lever 192 a suitable segment 196 is provided, which enables thelever to be locked in osition desired.

T e face of the driving-Wheel 8 is provided with a plurality oflaterallydis osed ribs or lugs 197, and these are supp emented 4bypointed dogs 1. 98, disposed intern: ediate thereof, the said give thesame the most advanta ecus This lever constitutes .a

dogs being preferably removably attached. These dogs are intendedespecially to be used where the im lement must pass over frozen ground,whic may be covered wit ice or snow.

The mode of operation of the im lement g will now `be described, itbeing un erstood that the implement would be advanced in the standingcorn so that the stalks of corn could pass into the convervingspaceybetween the noses 78. It then follows that by reasonof the fact thatthe snapping-table 27 is hung, upon the yokes 30 the said snappingtablewill then readilv adapt itself to the position y of the stalk. The lowposition of theshoes 76 operates advantageously-so as to faclhtate theraising of cornstalks that may have been forced down upon the ground. Asthe implement advances, the stalks come under the influence of the dogs88, and they operate to advance the stalks rearwardly, eventually passinthe same between the guide-springs. 89 an into the space between thedecks 28 and 29. As the movement of the implement pro resses the earscarried by the stalks will fina ly comeinto contact with thesnappingchains 35, and these operate to detach the ears, allowing thestalks to pass downwardly between the decks. In this connectionattention is called to the staggered relation of I OO' the brackets 50,which was mentioned in connection with the .means for mounting theguide-strips 40 and 41. By reason of this staggered relation if itshould happen that an ear of corn or other object becomes lod ed between the chains the same could be rea ilydislodged b forcing one or theother of'the clains outward y andaway from the other. This freedom ofmovement of the chains laterally is much enhanced by this arrangement;lbut this would be otherwise .if the brackets were located oppositely,for in this event should an ear of corn become lodged at the bracketsthere would be no possible movement whatever at this point. .For thisreasonthe modified construction shown in Fig. 11 is lsuggested, and whenthis construction is adopted the staggered relation will not be soneceslwith 4the ears, the sai sary. After the ears are detached from the.stalks theg will be caught b v the wings G1 of the snap ing-chain andwill advance up- Wardly therewith, passing eventually over the upperextremity of the snapping-table. They all upon the upper portions of thehusking-rolls and proceed downwardly by gravit at the same time beingsubjected to the hus ing action of the husking strips or strippers fA113 and 115. If any of the grain is shelled. by the strippers or bv theribs 111, this grain passes through to the separator, while the earswith the body of the grain thereupon pass toward the lower portion oftherolls and eventually ,drop into the receiver 148 at the bottom of theelevator. As the ears progress toward the 4lower portion of thehuskingrolls the horns 132 operate in the manner described to preventthe assing of the husks d) husks being automatically fed upwardly, sothat they will eventually pass through between the rolls in the vicinityof the upper ends thereof. The modeof operation of the separator hasbeen descrbed'very full hereinbefore, and it need onl be stated at th bo4y thereof ar'e ejected at the forward portlon, while-the grain whichpasses between the slats of the separator-belt gravitates rearlWardly uon the inclined bottom 139 and dro s 1n ue course into the receiver.

' pecial attention is called to the arrange- "rnent for mounting thehusking-rolls, consisting, as it does, in supporting them on have atendency to clog them and detract from their efficiency.
